I have been suffering with scar tissue (AF) for years. I am not sure where you are, but if you look at the bottom of my page, I have done the MUA's, PT, and had it cut out. It just grows back. The following is a report on AF by Dr. Frank Noyes of Cincinnati OH.http://www.kneeguru.co.uk/KNEEnotes/node/633
You might also search for "missmyknee"'s blog. She has some great information on here and is very (I am not) intelligent on doctors, procedures, etc.
Yes, AF is genetic is some cases. I have had 28 major surgeries including five knee surgeries when I was young, but no AF in any of my previous surgeries. Unfortunately, day 1 of my first TKR I started growing it. I was diagnosed as being infected, but it was AF. Each time they did a MUA or cut it out, it came back heavier.
I did have luck with extensive PT, but she would put steady pressure....not overwhelming or tearing it, but we slowly made progress. You might also look up www.astym.com
. I would suggest you try ASTYM as soon as possible. It works on some and reduces the scar tissue without surgery.
Make sure you consult with a doctor who knows what AF is and how to treat it. I think if your first OS excised the scar tissue, he simply made the body go into protective mode and it grows right back, but thicker.
This is the way the body protects your knee joint. If it is removed, it must be done in a manner so as to not cause the body to react by growing it back.
Mine kept growing until my body starting growing bone in the soft tissue to protect the joint. Now when I walk, it is like a sharp knife is in my knee capsule poking straight up into my knee.
Educate yourself before your next appointment.
